Starting issues only come into play when the motor is between 160 and 180 deg. so if your motor never sees this much heat no prob.

As far as idling issues all you have to do is adjust the carb richer than normal and in a blown app. the carb is usually fat at idle anyway. NA motors would have more trouble with idling than blown apps.

What happens is your firing the cyl to soon in real time, that's why there is an advance curve.

After 300 some distributor builds for marine application, I have come to rely on a fairly standard curve. 0 at 400 rpm ( cranking speed ), 10 at 750 rpm, 15 at 1500 rpm and max calculated advance based on initial timing at 2800 rpm. Total of initial and advance not to exceed 34 in most NA applications unless ya got some real good gas. These are degrees measured at the crank. Remember that degrees of advance at the distributor must be doubled to equal crank degrees of advance. IE, 10 in the distributor = 20 at the crank.

Careful how you say that. To us laymen, thats confusing. I mostly hear "10 in the distributor" as refering to how much mechanical advance is in the distributor based on crankshaft degrees. In other words, 10 in the distributor, plus 18 initial, equals 28 total. Never heard of it actually being measured "at the distributor" which is what your implying - is that just me??
